Is any way to detect changed MAC adresses? Someone taught change MACs peoples in my network and I have problems. E.g. Two computers working on one MAC, and one IP (static ARP and DHCP). WinXP is screaming some message... that two computers or more have the same IP. How can I find out who''s changed MAC?

Hi Couple months ago I started to have a strange problem with HTB. My setup is Fedora Core 2 + Pentium 2 233 + 128 MB of ram and its serving as a router. For some time since going to kernel 2.6 my HTB QoS Stalls for couple seconds, every couple minutes. If the connection load is bigger the stalling is more frequent and takes longer. I isolated the problem to be with HTB (CBQ works fine). The

We run a Hosting farm behind a bridge/iptables firewall setup running Gentoo with kernel 2.4.20-gentoo-r6, connected to a dual 15Mbps international internet pipe / , as this: Net Pipe --------- eth1 Bridge/Firewall eth0 -------- Internal Hosting Network lately we have been looking at htb to somehow control excessive usage from the users behind, but in our implementation there seems to be an

Hello all, Does anyone know of a methodology to build a route based on the inbound and outbound interfaces as opposed to ip addresses? We are essentially trying to forward packets from one interface to another without looking at the ip address. Bridging (brctl, br2684ctl) will not work in this case as the interfaces use different layer 2 encapsulation (e.g., atm0<=>eth0, or

Hi all, I have a firewall central which a control the download/upload bandwidth with cbq of 9 differents networks. Now i need some help from you. I would like to use mrtg+snmp to reports these bandwidth to show per ip, how? any idea? tips?

Hello Everybody, I have configured a Linux box that does traffic shaping. Its working wonderfully fine, just as expected...Now i want to measure the bandwidth consumed by each of my hosts....But I dont want SNMP to run on all the hosts[as required by MRTG] I used iptraf on my linux box, but it only measures the bandwidth on interface basis only.... I tried installing traffic-vis, its not working

We have a Linux box that is acting as the gateway to the internet for about 400 people, typically there are not more then 50 of them using the internet at any given time. We would like to provide different levels of access to different users. For example 128kbps to some users and 256kbps to others. We have considered creating a class and qdisc for each user (using htb) however we don''t

Hi, How can I set equal bandwidth of 512kbit downlink and 256kbit uplink for every single IP address of 254 IP addresses I have in my LAN? Regards, ro0ot

I'm trying to get MRTG up and running on CentOS, but the displayed http page says that I don't have permission to access /mrtg/ on the server. Here are my commands yum install mrtg vim /etc/httpd/conf.d/mrtg.conf /etc/init.d/httpd restart cfgmaker --global 'WorkDir: /var/www/mrtg' --global 'Options[_]: bits,growright' --output /etc/mrtg/mrtg.cfg public at 10.200.200.1

Hi All, After reading the sparse info and attempting to get this running, I'm unsuccessful and could use some guidance. I already have a MRTG server up and running serving hundreds of router interface graphs. I would like to add SIP/IAX channel graphs for all our asterisk servers. I'm running asterisk 1.2 and MRTG 2.4.17. I tried the script from http://karlsbakk.net/asterisk/ but get

I have created shell script for MRTG statistics of droped/rejected packets: ftp://slovakia.shorewall.net/mirror/shorewall/mrtg/ http://slovakia.shorewall.net/pub/shorewall/mrtg/ rsync://slovakia.shorewall.net/shorewall/mrtg/ example: http://slovakia.shorewall.net/pub/shorewall/mrtg/example/ It is not based on /var/log/messages (syslog), but iptables counter. A lot of packets are droped/rejected

Hi all. I am having an issue and quite frankly would rather not spend the entire next two days learning the entire snmp program. I am hoping someone out there has used MRTG and SNMP to make it work. I have both installed. Single server, polling itself. Question 1- does snmpd have to run as a daemon, or only run once so I can get OID and MIBs from it? Question 2- does anyone know the command

Hi guys, I'm using Centos 3.5 with Apache-2.0.46. i linke my mrtg from /var/www/mrtg to /var/www/html/mrtg so i did the command ln -s /var/www/mrtg. it worked fine last week but when i checked the mrtg today it say 403 forbidden.

Hi, i'm running CentOS 6.0 on my server and installed mrtg from the rpm-package mrtg-2.16.2 . I also installed the depending packages perl-IO-Socket-INET6 perl-Socket6 .... mrtg works fine with IPV4-Addresses. When i specify a Target by IPV6-Address (or hostname resolving to a V6-address) mrtg fails. Here i have a small sample-config for V4 which is working: LogDir: /tmp ThreshDir: /tmp

Hi, I have setup MRTG with 14all.cgi cgi script. I downloaded it from below URL. http://my14all.sourceforge.net/14all-1.1.txt and did only below 3 changes to that file. those can be seen in BOLDletters. # if MRTG_lib.pm (from mrtg) is not in the module search path (@INC) # uncomment the following line and change the path appropriatly: #use lib qw(/usr/local/mrtg-2/lib/mrtg2); use lib

i''ve installed mrtg to make graphics of the trafic from the interfece throw the snmpd, and the same with ipac witch put iptables accounting rules colect them and store, and gets the output, but the "problem" is that ipac graphics are 3 times smaller that the snmpd. Why??? i did catch all the trafic with ipac so no problem here, and i know that ipac/iptables is at level 3, and

I check system load like so: [root at server cron.daily]# w 10:07:33 up 4 days, 15:01, 2 users, load average: 4.22, 3.17, 3.09 I would like to to graph the 3.17 5 minute average with MRTG. Anyone know of some examples of doing this?

Ok, I'm having a major brain hemorrhage or something. I just can't get mrtg setup on my box. I've done it before and it's not like it's brain surgery but there's a mental block or something that I just can't get around. All I want to do is have a nice, simple graph of the traffic on the box and the gateway in the standard day/week/month/year thing. I've got the

I got itchy fingers over the weekend and decided to fix what wasn't broken and upgraded one of the older servers from Centos 5.2 to Centos 5.3. Following the recommended process of updating glibc and such before the rest, it appeared to work perfectly and rebooted without problem. However, MRTG 2.15.2 started complaining about unexpected values. I installed/updated both MRTG (2.16.2) and
